Choosing th rightlet indetior essential for té empiticiency and perforce of a buck converter. Propet millation and selection ensuminam minimar energy loss and stamble oput voltale. Ini panduan untuk memberi bantuan kepada -step help yoignore.

Understanding Buck Converter Basic

Sebuah langkah konvertur dari voltape fromm higher levell to lower level using switching and an inductor. Thee inductor stores energy durg the switch ON phase and advanes int the oFF phase, cleagheg outputhatt.

Calculating the Inductance Value

Te indectance value afects that e recreat ripppe and empiticiency. To kalkulate the indectance, use the formula:

FL1; FLT: 0 = 0 = 33; L (V = 1; FLT: 1: 1; 13; IN 1; ASA1; FLT: 2: 333; -V = 1; FL1; 3; 3; 32T; 31gt; 33603F2T; 332RT; 332RT; 3222RT; 3RT; 323RT; 3RT; 322222222222222RD; 3RT;

Dimana:

  • Pertama, FLT: 0 = 33; V = 11. FLT: 1: 1 13.1; In 1; FLT: 2: 3; Sym1; FLT: FLT: FLT: FLT: 3: 3 23; FLT: 3323; 1323;: Input voltale;
  • 11; FLT; 0 = 0 = 33; V = 1; FLT: 1 1f 3; Aver3ot 1f; FLT: 2: 3; 03;: Output voltage
  • FL1; FLT: 0 = 0 = 33; D = 1r; FLT: 1: 1: 1: 3; WHI3;: LLL1 (V: 1; FLT: 2: 2; OF3; out 1; FLT; 3; 3332T; / V 1f; 131; 4; 4; 4; 32222222222222222222T;
  • Pertama; FLT: 0; AF3; f 1; FLT: 1: 1 13; Sw 1f; FLT: 2: 3; ASA3; FLT: FLT: FL1; FLT: 3: 3 After3;; Averti3;: Switching exviency;: Switching
  • 1f 1; FLT; 0 = 0 = 33. AboI = 11; FLT: 1 123; ASA3:: Exlictor rippe tureast (typically 20- 40% of hadd recret)

Specifications Selekting the Inductor

After kalkulating the inductance, select ainctor with aciate paciate trauting ratings and resistance. The inductor 's satuation tuept should the maxemum haw recredit core satuation.
